JOHN G. MASSIE, OF BELLEVILLE, ILLINOIS.

HOSE-COUPLING.

Specification of Letters Patent.

Patented Nev. 26, 190'?.

Application filed January 14.1907. Serial No. 852.199.

To all lwhom 'it 'may concern:

Be it known that I, JOHN G. MAssrE, a citizen of the United States of America, residing in Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a full,.clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a hose coupling more particularly intended for use in connection with hose through which iiuids are conducted under. a higIi pressure and is especially valuable for the connection of sections of yhose through which compressed air is conducted to machines that are operated by compressed air. y, The' coupling is, however, adapted to be used in connection with hose through which water or any other iiuid is conducted.

Figure I is a view partly in elevation and 'p partly in longitudinal xsection of the coupng shown uniting two sections of hose.

Fig. II is an end elevation of the female' memberof the coupling. Fig. III is an end elevation of the male member of the cou lin and the binding nut that connects t e ma e and female members.

A desi nates sections of rubber hose of uniform t ickness.

1 designates a sleeve having an interior shoulder 1a and a lain unobstructed interior surface into w ich the end of the section of hose is introduced and against the shoulder of which the end of the hose is seated and which is provided at its forward end with an interiorly screw-threaded neck 2.

3 is the male member of the coupling which com rises a long cylindrical screwthreaded siiank 4 that is ada'ted to be screwed into the neck of the s eeve 1 and terminates in long tapered portion 5 that is also screw-threaded and is adapted to enter into the section of hose that is seated in thesleeve 1. The male member of the coupling also comprises a conical art 6 located at its forward end and at the ase of which is an annular rim 7. The male member is provided with a channel extending longitudi- ,nally therethrough which is preferably of uniform y diameter from end to end of thev member except at its forward end, at which point the channel 1s made non-circular as seen at 8, Figs. I and III in order that a suitable implement may be introduced into this end for the purpose of turning the member in the sleeve l after it is placed in screw-` the wall of the-sleeve surrounding it, this condensin r the hose and iirmly binding Ait between tIie impinging members. The tapering end of the male member shank being threaded, its threads enter into the texture or substance of the hose and act with locking action thereupon in addition to the binding action exerted by the shank and the sleeve surrounding the hose.

9 designates a nut which surrounds the male member ofthe couplin and is provided with an internal ange 10 t at bears against the annular rim 7 of the male member. The forward end of .this nut which surrounds the conical art of the male member is threaded interior y.

11 designates the female member of the couplin which is threaded externally and is adapte to be engaged by the nut 9. This female member is provided with a channel which is'in part conical, and is com lementary to the, conical part 6 of the ma e member of the coupling that enters into said conical part of the channel in the female member. It wil-l be seen that when the nut 9, if placed in threaded enga ement with the female member of the coup ing after it is fitted to the conical part of the male member and said nut is turned in the proper direction, the

male and female members of the coupling will be drawn together in a manner to effect a tight joint between them. member 11 of the coupling is provided with a screw-threaded shank 13 similar to the shank of the male member of the coupling and terminating in a screw-threaded conical portion 13a whichis surrounded by a sleeve 14 having an interior shoulder 14n, a screwthreaded neck fitted to said shank and in which a section A of hose is introduced to be bound or clamped therein in a manner simi- The female lar to that in Which the section of hose associated With the male member of the coupling is bound or clamped.

I claim:

A hose couplingcomprising a sleeve formed With a lain unobstructed interior surface,

l With an lnterior shoulder at its inner end, and

With a neck having a cylindrical interiorly screw-threaded throat, a connection member formed, at one end, With a long cylindrical cxtcriorly screw-threaded channeled shank, iitted to saidthroatland With a long tapering eXteriorly `screw-threaded portion extending Jfrom the channeled shank and at its other end with an annular rim and With a conical part, a second connection member formed, at one end, With an external screw-thread and a conical channel tted lto the conical lrt, and, at its other end, with a long cylin- 'cal eXteriorl' screw-threaded channeled shank, and Wit a long tapering exteriorly screw-threaded ortion extending Jfrom the channeled sha a second sleeve formed with a plain unobstructed interior surface,k

with an interior shoulder at its inner end, and With a neck havin a cylindrical interiorly screw-threaded tr channeled shank of the second connection member, and a coupling nut formed with an internahiiange and an interior screw thread fitted to the external screw-thread of the sec* ond connection member.
